How well does your OpenID Provider stack up?
There are increasingly more specs in the OpenID space, and many of the extensions rely on XRDS documents to
publicize support. To help enable that, I’ve been looking to update my yadis plugin for WordPress to automatically
include the correct protocol support for the major OpenID Providers. Of course, in order to do that I have to actually
find out what all protocols they supported, so I pulled out JanRain’s OpenID library and began writing
my script. I first checked all the different ways in which you can request an XRDS document… using a request header
of Accept: application/xrds+xml
, looking for a response header of X-XRDS-Location
, looking in the <meta />
tags,
etc. Once I had the XRDS document, I checked which protocols they advertised support for, and compiled that all into a
nice little table.
See the OpenID Support Table.
The results are about what I would expect… there are just a few front-runners that are really making an effort to support the emerging technology (likely because they are also involved in authoring these new protocols). Everyone else is supporting some version of the (technically, still current) OpenID 1.x protocol and about half have also added sreg support. That same half have basic XRDS support (since it’s required for sreg), but none of them are doing more than the most basic XRDS discovery method. Only a couple of the leaders are supporting the more advanced (and much faster) XRDS discovery.

Awesome work, this is just the kind of thing the community needs.
It would make a great starting point for the kind of community-driven provider comparison site that has been talked about on the lists.
As 2.0 gets closer to ratification, I look forward to seeing how fast things actually get adopted.
Great work on the table!
Sxipper does support a draft of AX. Check out the FAQ "Where can I use Sxipper's OpenID Attribute Exchange?" at this URL: http://www.sxipper.com/faq_openid
Great Chart and looks like your move will be a smart one. Wish I knew more about the entire Open ID subject, but I'm still learning. Will keep up here to see the progress. Keep up the good work!!
Peace!
Love your work on the chart! I wish I knew more about Open ID, like why it just took my post away to you....arghhhh
Great info on your site and I will be checking back often, esp. regarding your change to Vidoop. (sp ?)
Keep up the great work!!
